Mastigoproctus colombianus

Mastigoproctus colombianus range from 45 to 65 millimetres (1.8 to 2.6 in) in length. Color brown and red-end legs.

Like the related orders Schizomida, Amblypygi and Solifugae, uropygids use only six legs for walking, having modified their first two legs to serve as antennae-like sensory organs. Whip scorpions have no venom glands, but they do have glands near the rear of their abdomen that can spray a combination of acetic acid and octanoic acid when they are bothered.[1] The acetic acid gives this spray a vinegar-like smell, giving rise to the common name vinegaroon.

Whip scorpions are carnivorous, nocturnal hunters feeding mostly on insects and millipedes,[1] but sometimes on worms and slugs.

Mastigoproctus colombianus are found in tropical and subtropical areas of Colombia. They usually dig burrows with their pedipalps, to which they transport their prey.[1] They may also burrow under logs, rotting wood, rocks, and other natural debris. They enjoy humid, dark places and avoid the light.
